Abstract

L'invention se rapporte à un dispositif d'écrou pour un mécanisme vis-écrou destiné à appliquer un effort axial de serrage sur un piston de frein (50) à partir d'un entraînement rotatif, au sein d'un d'actionneur motorisé. Le dispositif d'écrou comprend un fil métallique (20) comprenant une portion enroulée (21) de sorte qu'elle forme un enroulement hélicoïdal apte à être enroulé autour d'un arbre fileté d'actionnement (40). Le fil métallique comprend une portion d'arrêt en rotation (25) du fil qui dépasse radialement autour dudit enroulement (21) de façon à coopérer par engagement de formes avec un logement (52) du piston pour arrêter la rotation dudit enroulement. Le dispositif d'écrou comprend un manchon d'actionnement (30) entourant la portion enroulée (21) qui est insérée dans une rainure hélicoïdale dudit manchon. Le manchon comprend une face d'appui axial pour appuyer au moins en fonctionnement sur une face arrière d'appui du piston de frein. Le domaine de l'invention est celui des systèmes de freinage pour automobiles.
